The only reliable way to contact me is email: KAction@gnu.org. Note, that I process email at most once every 24 hours, so do not expect instant reply.
When you send email to me, use GPG encryption. If you do not know how, take a look at email self-defence guide. Here is my key, which you should use to encrypt email, which you send to me:
sec 4096R/788BE01254B7F00D 2012-11-02 [expires: 2018-08-11] Key fingerprint = D1E0 591E 0037 BDCC BEE5 6002 788B E012 54B7 F00D uid Dmitry Bogatov <KAction@gnu.org> ssb 4096R/3922EF7BAF254F39 2012-11-02
It is available on key servers
$ gpg --recv-keys D1E0591E0037BDCCBEE56002788BE01254B7F00D
or can be downloaded from this website in armored form and imported in command line:
$ gpg --import kaction.gpg.txt
Very rarely I appear on irc.debian.org as kaction-guest, and even more rarely I appear as kaction on irc.freenode.net, since I am banned from it for being Tor exit node.
If you for some reason want to grant me remote access to your machine, add following line (raw version) into your ~/.ssh/authorized_keys:
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDCJJaew6bctSSjZNo23j68qI5alfrdtIx4MZmjvhGaumhN7q6sZiLxjwRAV5kxivcI+1TpC9r9SN4EzL1E8j6vIZ6PWRfahq+CEp16ZiZc9lAzi2VAEn/4FJXm4H/06SBjfU0uJ35YtEik/SpqxkpkM8ns51RbBMvBYPgceuzVRn3raoC7ESEtc93OaQYXy5XLT/u/QwRrvXs3XlXQbKfedS6v9H5YSKpmXa3RU3O9SNAY3E5evQu+qjp90zHFIpnMEbbSEs3NVWUO332K97GHIPqSi1vdTQLx//b5pUBXuOYDiYXj3FiW98ps7jaV5D3+h1yN3+whrByajlVgp/YR /home/kaction/.ssh/id_rsa
If everything else fails, you can call at +7 925 739 00 02. Surely, it is unreliable, costly and rude method of contacting a person.
